High Current Booster The current output of T 2000 can be increased to up to 2000 A with a new type of optional booster controlled by the T 2000 control unit. The BU 2000 option is an innovative design concept that allows to avoid the power losses due to long cables connections. To achieve this, the BU 2000 transformer is placed very close to the device under test (CT primary side, Circuit Breaker main contacts), thus avoiding losses on the high current cables. The BU 2000 is then connected with a long (20 m) low current cable to T 2000 unit. The option can use one, two or four transformers, as a function of the maximum test current and/or the test duration (see table below). In case of 2 to 4 BU 2000 units, an Interposing Module is necessary.
